JOHN ROYDEN PEIRCE, OF NEW YORK, N- Y., ASSIGNOR .TO INTERNATIONAL BUSI- NESS MACHINES CORPORATION. OF NEW YORK, N. Y.; A CORPORATION OF NEW YORK.

Application filed June 3,

This invention has for its object the provision of novel means for transpo'sing a reading from coml'iinational holes of a perforated record to the cont-rolled elements of :i pivrfoiai'cd record machine.

lleretofore machines controlled by perforated records have comprised so-called llollcrith type machines and Peirce type machines. The former use the digit forni of perforation and the latter utilized multiple or combination hole systems in their controlling records. Both systems have advantages, and in general it may be stated that the Peirce form of record permits a r greater amount of data to be placed upon a record of given size than with the Hollerith system.

Heretofore in utilizing Peirce records in controlled machines, it has been the general practice to allocate fixed fields or zones upon the card to predetermined and controlled machine elements such as accumulator type carriers and the like. Accordingly it has not' heretofore been possible with Peirce machines to obtain the exibility which has generally been secured with Holler-ith type machines which employ electrical circuits controlled by the index point perfor-ations in the cards.

The present invention has for one f its objects the provision of a construction which will permit so-called Peirce type of machines utilizing combinational hole systems of. perforated records to operate with the flexibility heretofore only obtained in Hollerith machines u sing digital perforated records.

A further object of the present invention resides in the provision of a novel combination of devices for reading combinational hole records, transposing such readings into differential linear readings which last readings are thereafter adapted to control certain electric circuits which extend to magnet devices.

A further object of the present invention resides in t-he provision of novel combinations of devices for iirst reading combinatioual hole records, secondly converting such multiple readings into single linear readings, thirdlyY utilizing said single linear readings to control circuits at differential times in the machine cycle and finally in controlling the TABULATING APPARATUS.

lThe tabulator. printing and adding action shown in the present application is of the type heretofore devised by me and more specifically described in my copending application Serial No. 693,572, filed February 18, 1924.

Broadly it includes a plurality of racks which diierentially position type 21 and also add in the amount to an accumulator. The racks are raised synchronously by means of suitable 'springs 150, this operation being permitted at the proper time in the cycle by meansl of the vcam devices 151 or main machine drive shaft 34. The racks are suhsequently restored by this cam mechanism'. to normal or lower position. All of the parts are more fully described in my copending application and are of the usual form 1n a circuit` diagram of the tabulating machines of the Peirce type.

= Printing. is secured upon the record carried'ion'the platen roll 23 byoperation of the hammer devices 24. The differential l movements of the racks are 'controlled by magnets 25, there being an individual magnet for each record card column'and for each The magnets individually control latch devices 26 which arrest the racks at differentiall elevated posi-tions. p

Totals are taken by'reversing the accumulator-l shifting.: mechanism '(see theparts designated 27,Fig.'3). To set the parts fo; taking-totals a button or slide- 28 (Figs. 1 and 3) is provided. To set the parts for "i total'itaking this slide is pressed in to the positionrshownfin Fig.l 3. "A suitablel shoulder on'lthe slide opens contacts 29 andin addition an arm.'30`shown in dotted lines is rockedclockwi'se, thus depressing a'link '31 (Figs. 1 and 3) against the action of the restoring spring 31:.. The' link carries a block or projection 31b which is adapted-to depressand disenga-ge a pivoted spring rcturned' clutch 'dog 32 (Fig. 1) and thus disengage the drive shaft 33 for the card feed from the main drive shaft 34 of the tabulating section of the machine. During regular printingand tabulating operations this clutchiis engaged.

Drive for card feed and tramsposiug .section of the machine..

Fixed to the shaft 33 is aber cam 35. A follower 36 (Fig. 4) co-operates with thc cam and rocks a rock shaft 37 to which is fixed a bevel gear 38. Meshing with this gear is a second gear 39 which is fast to the end of a rock shaft 40. The movement ot this rock shaft is utilized for feeding the cards and for advancing the pins into contact therewith.

Referring to Fig. 4, the card feed section ot' the machine includes the usual card supply and discharge pocket-s 4l and 42.- Intermediate the card supply and discharge pockets is a. reading station.

Like previous machines utilizing combinational hole cards the cards are advanced troni the card supply pocket to a reading station. Here they remain for a period of time n'hile thc pins are advanced into contact with the cards and take aV reading of the perforations. Subsequently the pins are \\.'itlnlran'n and the cards are again advanced to the discharge pocket 42. For advancing the cards from the supply to the discharge stack a suitable Dicker and card clip carringe mechanism is provided.4

Referring to Fig. 5, at each-side of the card path there are provided'two slide or guiding posts 43. rlhe interior ofthese posts is hollow Vto permit passage therethroughof thc picker actuating rods 44 (see Figs.'5 and The picker'bar 4 5 is attached to' these rods 44 in the manner-shown in 'Figfg Re# ciprocationcf the picker bar is effected by means of t-he linkage 46 ishown'infFiggGi This linkage is actuated by rocking shaft 47 (Figs. 6 and 3) to which shaft is' attac-hed a crank arm 48 (Fig. 3 which in turn through link 49 is attached-to la crank 501 which is fast to rock shaft (see Fig-5).' 3

The clip carriage'compris'es a franie'52 'I slidably mounted upon the guide rods 43. Reciprocation'otthis frame is eiiected by means of a linkage 53 which extends toand is ixedly connected.v to therock shaft40 (see Figs. 5 and 4). -|The clip mechanism is ot the form usually used in machines of this class and comprises upper-pairsl of clips 54 andlow'erpairs ot'fclips'55 (see' Fig.` 6'). r,The picker advances the card into-the jaws ot' the upper. clipspivhereupo'n theseclips close and subsequently upon-'the lowering of the frame 52 the-upper clips draw'acard between guide plates 56 and 57 (Fig. 4);(4 '.l-o arrestt-ire card at the'properireading posi# tion and strip itfrom the clips card stops or abutment pieces-58 are providex- These abutment pieces are of pivotal construction lacing suitably mounted inatixed frame portion ot' the machine and-arc normally retracted from the card path bymeans of springs 59.' At-the'proper time.in"the'cyclc. of the machine camming elements 60-are raised Vupwardly- -thus forcing the stop pieces 58.0ntwardly and into thepathfof :he lower edge of the card (see Fig. 7)'. 'the cam pieces 60 are preferablyV carried on a link (S1, Link 61 is slidably mounted "for vertical movement as adjacent back plato 56. as shown in Fig. 4. This link 6l pren-hind with two pins 62 and 63.. The fx-anic 52 ot the card carriage carries a pin iE-L which vertically aligned with the pins 62, 63. Upon the iframe 52 being elevated till and approaching ils upward extent of movement pin (Si will strike pin (S2 and elevate the link 6l thus permit-ting the card stoppieccs 5S to be retracted. 0n the loweringy of the card clip carriage the pins (il will contact. against pins 68, thus shitting link (il in a reverse direction and forcing the stop pieces outwardly into the position shown at Fig. 7.

The mechanism for operating the clips is ot' the forni usually used in machines ot' this class. rl`he clips are substantially identical in construction and one will be described.

Referring to vFigs. (S and 8, the clip mechanism comprises a pair of clip members G5 and 66. Clip member is fixed to the clip shaft 67, which shaft is suitably journaled in the frame of the clip carriage Clip member 6G is connected to the clip member 65 by a tension spring (58. Member G6 has a tail portion G9 (Fig. l) which projects under a shoulder portion tixed to the clip carriage .frame Referring now to Fig. 3. 'ixed to the clip shaft 67 is abell crank member 71 which, upon the upward movement of the clip cai'-, riage, is adapted to strike a camming meniber l2 thereby rocking bell crank 7l in a counterclocluvise direction as viewed in l? ig. 3 and in a clockwise direction in Fig. 6. Fixed -to the bell cranks 71 are links 73 which rock the lower clip shafts and cau-7e a concurrent operation of the lower pairs ot' clips. `The effect of rocking clip .shaft-s 67 is to rock 'clip member 65 in a clockwise direction in Fig. 6. Through the tension of `spring 68 clip member 6G is rocked in a -similar direction. until .further rocking movement o this clip is prevented by its tail -69 contactingr againstixed stop 70 (Fig. 4).. Subsequent rocking movement opens the clip jaws to the position shown in Fig-6. In Fig. G the clips 54 and 55 are not shown in their extreme :uppermost position. In this figure the jaws are both shown open. The' subsequent further upward movement causes a member which is fixed to the frame 52 to engage a pivot dog 76 and rock the latter so as to release it from the locking engagement with cam member 72. i

Referring to Figs. G and a. spring 77 at its upper end is connected to Athe link 7 3 and this spring normally tends to rock the clip shaft in a clockwise direction (Fig. 6). The lower end of this spring is fixed toa dog 78 which will hereafter be described.

The action of spring 7 7 together with the clip action previously de'cribed causes the upper clips 54 to grip the car-:l which has been advanced by the picker. Concurrentbyr the lower clips 'i l grip the card which has lireviousl)r been at the reading station. lVleans must be provided for preventing ex cessive rocking of the clip assembly in a BEST AVAILABLE con". a

counterclockwise direction about its pivots a't'tcr it has gripped the card. Referring to Fig. 6, the member 78 which 1s pivoted on the clip carriage provided with a locking projection or shoulder 79 which engages a notch 80 ina bell crank 7l. As lshownfin Fig. G, there is a slight` clearance between projection 79 and the en d ot' notch 80. Consequently members 7la cali only rock to a limited extent after the cam 72 has been released from its locked condition. Thus the slot 8O prevents excessive rocking of the clip assemblies.

rl`he description heretofore given has dcscribed one clip operation but it will be understood that there are similar parts at the other side ot' the card, and as to these a similar inode of operation applies. The clip carriage is now lowered thawing the card which was previously at the reading station down to its storage stack whereit is stripped from the clips by means of the base plate 8l. Concurrently therewith a new card is drawn from the supply pocket l1 and advanced to the reading station where it-is stripped by the. displaceablc stops 58.` Then the clips-again move in an upward direction it is: necessary that they be displaced vout ofthecard path to prevent pushing the card .which is at the reading station in an upward'direction. To thus displace the clips out o-'the path the following mechanismlis provided z i Referringto Fig. 3,A these members 78 when the clip carriage makes its extreme downward movement conta-ct with-'i stop members 82- (Fig. 3) thereby rocking member 78 sufficiently ina counterclockwise direction (Fig. 6) 4to releaseshoulder 7 9. from the notch: 80,' springs 77 being now under tension thenfact toturn the'clip assemblies as a.unit-out of theA card-path. :The clips are then moved upwardly and the' action is repeated for the.: next card and so on.

For each card column fourpins 83 are provided. .-The'se pins are guided at one end in frame 56 and are adapted to be projected from aligned .openings in fralnexor plate The 'p'ins 83 are guided at their" rear ends in a fixed frame 84. and are normally pressed to the right in Fig. 6 by-means of individual springs 85. -The pins extend beyond frame 84 and are'provided 'with collars 8G which abut against a slotted frame or comb member 87. The purpose of this comb 87 is to restore the pins 83 after a reading is taken and reapply the tension to springs In addition it may be stated that by advancing comb 87 to the right the pins are permitted to advance in a similar direction. As usual in machines of this'type only such pins will advance as-encounter lil 'w described. 1

holes-inthe card.-v To actuate the comb plate 87 the following mechanism is provided. Comb plate 87 is fixed to a rock frame yS8, which v frame is suitably pivoted upon a-rock shaft 89 in the frame of the machine.- The rock frame 88 is actuated byxmeans ofav bell crank 90 which has a pin and slot connection with the frame 88. Bell crank 90fis suitably pivoted and has connected'to it:alink-91,which link` at its lower end-connects to a lever 92 which is pivoted at its centerto a fixed frame member 93 (Fig). Lever .92 `is provided with a follower roller'94` cooperating with a ralm 1e lever-'92 is' kept in Contact with the follower` by-a suitable operating spring 96 (Fig. 5). Upon the-rocking of rock shaft at the proper time'in `the'cycle the pin comb 87 will be actuated topermit the advance of the pins-'or restorethem as the case may be. The pins'83 when displaced to the right are 'adapted' to-disp'lace stop pieces and, as usual, in machines of this character there is :inflexibleconnection provided between the pins Aand stop-pieces to permit the pins to be `restored '.without restoring the stop pieces.'y .Referring to- Figs. i and 8, the

BEST'AVAILABLE COP\ i. e., extreme upper position with no stops withdrawn as shown in Fig. 4; the comb may be dropped one step, two steps or three steps as shown in Figs. 8, 8*, and 8, respectively. In addition to the movable combs 103 a fixed or dummy comb 105 (Fig. 11) is provided with each group of two movable combs 103. This comb is fixed in a suitable manner in the frame parts of the machine and the movable combs 103 are suitably guided for vertical movement and are normally drawn downward to their stop positions by means of springs 106 (Fig. 9).

In order to convert the combinational hole readings into a linear reading peculiarly positioned notches 107 are provided on the fixed and movable combs 105 and 103. The arrangement of these notches is such that a notch in each comb will align with a fixed line and corresponding;- notches in other combs will also align with this line for each differential displacement of the combs. Thus in Fig. 11 the fourth notch from the bottom of one comb is in alignment with the fourth notch from the bottom of the next comb and the corresponding: notch from the bottom of the fixed comb. rlhe arrangement of the notches is such that for each card reading there is a different open alignment of notches, In addition to providing individual alignments for the different numerals from zero to nine, I also providean alignment of notches which is effective when all of the pins advance, which condition takes place when there is no card present at the reading station. In the. construction described the movable combs are provided with' eleven notches and the fixed combs with ten notches. Thus there are ten different lineal alignment positions of these notches. These aligning positions are equally differentially spaced from each other so that if a member is passed over the face of the combs and allowed to drop into the notches it will drop in after travelling differential distances.

It will be understood that for each card colulnn there are two movable combs and one fixed comb constituting a group. By varying combinational movements of the movable combs with respect to the fixed comb it is possible to get ten different alignment positions corresponding to the digits and zero. If no card is present both movable combs will drop down and there will be an additional alignment position secured which is secured b r different notches but which in point of' location is the same as the alignment position which would be secured for Zero, i, e., when no holes were perforated in the card.

T he mechanism for reading the alignment positions of the combs will now be described.

lReferring to Fig. 10, it will be seen that 1,623,204 BEST AVAILABLE COP\ there are several groups of movable and fixed combs 103 and 105. Cooperating with each group of these combs is a springpressed pawl 108, which pawl is carried upon an arm 109 (Fig. 9). One arm 109 is provided for each pawl 108 and for each group of movable and fixed combs. Thus there is one arm 109 for each record card column. Each arm 109 i-S pivoted at 110 to a supplementary arm 111, one of which is provided Jfor each arm 109. Arms 111 are pivoted upon a common pivot 112 which is suitably' fixed in the frame of the machine. Arms 109 are drawn downwardly by individual springs 113. Normally these arms 109 are all held in upper position by means of a bail 1147 which bail is suitably journalled in the frame of the machine as shown in Fig. 10. To actuate the bail and rock it clockwise from the position shown in Fig- 4 a linkage 115, 1167 117, is provided having a follower' 118 coo erating with a cam 119 fast to shaft 33. n the operation of the machine once per card cycle bail 114 will `be lowered and this motion will be in syn-- cl'ironisiu with the elevation of rack bars 20 previously referred to. At the time the` pawl 108 finds a commonly aligned set of notches the pawl will dropinto an aligned .notch opening and thus arrest further descent of the right hand end of thearm 109. Subsequently' the arm 1109 will rock about the top of the pawl at its pivot carrying down the left hand -end of the arm 109,-A lowering the pivoted pin 110 and causing the corresponding supplementary; arm 111 to rock in a counter-clockwise direction about its pivot 112. Fast to each individual supplementary arm 111 is a contact actuating wire or rod 120. Each element 120 carries at-its upper end a piece of insulation 121 cooperating normally with a contact blade` 122. Thus upon. the moving downward of the element 120 the contact blade 122 will operateunder spring actionand close contact points .123. 4These contact points 123-i just closed establish a circuitto the controllingmagnet 25. (Figs. 2v and 13) and arrest further outward movement of the rack.

bar. Thus the closure of the contacts is affected at different vtimes depending upon the alignment position of notches for pawls 108...

It will be understood that until the arm.

of the arms 109 the springs 113 will have sui'iicienttension to overcome springs 124 and permit contacts 123 to close. Itwill be understood that there is one contact blade 122 Jfor each card column and the contact point 123 carried by each of these contact blades is adapted to establish contact with common bars 125.

1t will be understood that for each numeral in a particular column there are four possible hole spaces and four analyzing pins 83 (seeiFigs. 4 and 12). Each group of four pins variously controls stop pieces 99, 97 and 98 (Fig. 8). There are two groups of these stop pieces (see Fig. 4) which cooperate respectively with the two movable combs 103. For each pair of movable combs there is a corresponding .fix-ed comb 105 (Figs. 11 and 10). Each group of two movable combs has cooperating with it an individual pawl 108 which through the instrumcntalities previously described assumes dili'erential alignment stopping positions and thus controls thecstablishment o the circuit to themagnet 25 which controls the difier-` ential position oiitthe rack bars 20 for the corresponding card column. It will befurther understood that pawls 108 for different card columns may. reach their so-called alignment. positions .atdiiferent times and thus establish the controlling circuitsto mag-l nets 25 at diiferent times'relatively to the timing ofthe raising: cycle of rack bars 20. The -mechanis1n just -described constitutes-a transposing mechanism adaptedto derive combination hole readings from perorated recordsand to convert each combnational reading intol a' timed reading which'may impart aitimed How. ofcurrent through a circuitto a. controllingl magnet. Provision is made for reading 'all the com` binational hole readings simultaneously and for ldelivering the controlling current in1.

pulses at the same or dii'erent times to the controlling magnets depending upon the value,.of .the combinational hole readings which are made by the analyzing devices. Preferably the readings or analyzati'on of the' card. readings is vmade mechanically and the transposition of the readings to a timed differential lcontrol of the contact devices is also effected mechanically.

y Referring now to -the circuit diagram the individual contact blades 122 are wired to plug sockets 126. On this plugboard sockets abling certain contact blades or record card columns to be plugged up with multiple connections.

The type carrier 20, (Figs. 2, 13 and 14) 4is adapted to rise synchronously with the rocking movement of the arm 109, (shown inFig. 9) so that when the said arm 109 is stopped by the notches 107 causing closure of contacts 123, the resultant energization of magnet 25 will rock its armature 25 thus releasing the latch 26, permitting the latter to be actuated by its spring 26a into cooperation with a notched member 2On fixed on the type carrier 20. The type carrier will thus be stopped in a position which will present at the printing line the type corresponding to the value of the combination of notches 10T which caused stoppage of the rocking arm 109. The movement of the latch 26 to the right as viewed in Figs. 13 and 14 also releases the slide 130a permitting the latter to be moved to -the right b y its spring. 130" thus permitting contacts 130 to open.. .Thisbreaks the circuit through magnet 25 as will be observed in connection with Fig. v15. Contacts 130 are adapted in thisway to open before the arm 109 is returned to its normalI position and contacts 123 are again opened. The object of contacts- 130 is to break the circuit as soon as magnets have performed their function.

The tabulator circuit is of the usual form and it may be stated that current is derived from a supply source 133. A double pole switch 134 when closed establishes a circuit to points 135. Connected in circuit to the point-s 135 are-two contacts 136 and 137 and in addition there is a pair of contacts marked 29. Contacts' 137, 136, are the usual cam contacts used in tabulating machines and serve to supply the current only at the proper time in the card cycle and interrupt at other times. Contacts 29 are the so-called total contacts previously referred to and these contacts open up during a totaling operation and prevent any control of the raising of the racks by the magnets 25 dur ing this time in the cycle.

After the reading has been taken from the displaceable and fixed combs and after the contact controlling arms 109 have been restored to their normal position shown in Fig. 4,-means is provided for restoring the displaced combs to normal elevated position. Such restoration is effected by means of a bar 138 which extends under the lower ends of the comb, which bar is elevated by means of a link 139 connected to a pivoted follower 140 cooperating with cam 141 fast on 'shaft -ing said combinational readings to single differentially timed readings, and means controlled by the aforesaid differentially timed readings for establishing electrical controlling circuits at corresponding dilferential times.
